This is an attempt to implement automatic conversion of LuaLaTeX inline and display math expressions into MathML code to aid with tagging.
It works best with unicode-math, but it can also be used with traditional math fonts if mappings to Unicode are provided.
Run l3build install to install luamml into your local texmf tree.
Add \usepackage[tracing]{luamml-demo} to print MathML to the terminal or \usepackage[files]{luamml-demo} to generate separate files with MathML output.
Alternatively it can be used with latex-lab to automatically integrate with tagging infrastucture.
